But now some of them want to get rid of him because they say he's a health risk.
He bites legs and is so old he sometimes pees on the chairs. He even fell asleep on a chopping board recently!
A spokesman said children come to the station to see the fire engines and the cat's mess was a health problem.
But other firemen there say he's part of the team. They've started a Save Angus campaign and even had t-shirts printed to try to keep him!
